Frequently Asked Questions
Q: What is the exact size of the SU 459-XL-A load wheel?
A: The SU 459-XL-A measures 6.000 inches in diameter and 3.000 inches in width (152.40mm x 76.20mm). It features a 2.25 inch inside diameter with a 0.78 inch bore depth and 2.4404 inch bore outside diameter. The 3/8 radius tread profile provides moderate contact area for standard electric lift truck applications.
Q: Can I use the SU 459-XL-A on high-capacity forklifts?
A: The SU 459-XL-A is engineered for general-duty electric lift trucks with moderate to standard load ratings. For high-capacity or heavy-duty applications, verify that your truck is rated for 6 x 3 wheel specifications. If your application requires wheels rated for more than 2500 lbs per wheel, consult the manufacturer or consider larger-diameter alternatives like the SU 487-XL-A (8 x 2.5) which offers greater load capacity.
Q: What material is the SU 459-XL-A tread made from?
A: The SU 459-XL-A tread is made from Cushothane XL, a polyurethane compound that provides good floor protection and wear resistance. This material resists splitting and chipping better than standard elastomers and operates effectively on concrete, tile, and vinyl floors without damaging floor surfaces.
Q: Do I need a press tool to install the SU 459-XL-A on my truck?
A: Yes, the SU 459-XL-A wheel assembly must be pressed onto the steering or load wheel axle using a bearing press or dedicated wheel press tool. Do not attempt to hammer the wheel onto the axle, as this damages the internal bearing seals and bore. Verify that your press setup is calibrated for the 2.25 inch inner diameter and 0.78 inch bore depth to ensure proper seating.
Q: What is the maintenance interval for the SU 459-XL-A wheel?
A: Inspect the SU 459-XL-A every 250 operating hours for tread wear, cracks, or separation from the core. Grease sealed bearings every 500 operating hours if equipped with greaseable shields, or every 1000 hours if equipped with sealed (2RS) bearings. Replace the wheel assembly when tread depth is worn to less than 0.25 inches or if internal bearing play exceeds 0.05 inches.
Q: Is the SU 459-XL-A compatible with older electric lift trucks from the 1990s?
A: Compatibility depends on your specific truck model and axle configuration. Verify that your truck is originally equipped with 6 x 3 wheels and check the steering column axle diameter against the 2.25 inch inside diameter spec. Many older trucks use different hub widths or bearing configurations, so confirm bore depth and outside diameter before ordering. Cross-reference your truck manual or contact the lift truck manufacturer with the serial number.
